Question 599104: I believe I did the problem correctly, but would like some assurance.
Proving a trig identity: cosx/cscx-sinx=tanx
cosx/cscx-sinx
= cosx/1/sinx-sinx
= cosx/1/sinx-sinx/1 x sinx/sinx
= cosx/1-sin^2x/sinx
= cosx/cos^2x/sinx
= cosx/1 x sinx/cos^2x
= cosxsinx/cos^2x (cancel out)
= sinx/cosx
= tanx Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! You are correct. Nice work. The only issue I would point out is the use of parenthesis would make things look a bit cleaner.
